I seriously doubt Mp3Tag could break a mp3 stream, but the fact is that i usually check my mp3 files before and even after using Mp3Tag and usually the latter does not create corrupted streams, but does not fix them either.
I know both mp3val and MP3 Diags do detect wrong tags, and even mp3 stream frame errors. being MP3 Diags for "Wahnsinnige leute".
So, the first question: Can anyone establish some guidelines on how to use MP3Tag together with mp3val and MP3 Diags, to minimise errors in MP3 files? I mean, do not just say "use/try/check mp3val/MP3 Diags", but HOW to use them. A recommendation on a "custom transformation list" in MP3 Diags, to be used together with MP3 Tag, would be very useful.
A simplified guideline could be sth like 1. save/export all tag info to a file, 2. fix tags with mp3val/MP3 Diags (default 'custom transformation list' in MP3 Diags could do), and 3. recover all tag info from exported file into mp3 streams.
The second one: is it really safe to use mp3val/MP3 Diags? Or shoud we care about the changes they make? I mean, is "garbage" really "garbage"? In other words, can "garbage" sound like music, or just like "garbage"? I'm about to make the acid test on this, but it'd be helpful if someone did it already.
